Airtel Nigeria is adding customers, selling more data, and generating higher earnings. Yet a decline in its quarterly operating margin suggests that rising demand is not translating into stronger profitability at the same pace.

The company’s mobile-services Earnings Before Interest, Taxes, Depreciation, and Amortisation (EBITDA) margin fell from approximately 58.8% in the first quarter of its 2027 financial year to 57.5% in the second. Although its half-year performance remained significantly stronger than a year earlier, the sequential decline points to the growing challenge of managing operating costs while expanding capacity to accommodate rising traffic.

That tension is becoming central to Airtel Nigeria’s growth story. As data consumption accelerates, the operator must balance network investment and rising operating expenses against the need to sustain margins and generate cash. The question is no longer simply how much demand it can capture, but how efficiently it can convert that demand into lasting financial returns.

For Airtel Nigeria, the challenge is to turn Nigeria’s appetite for connectivity into earnings and, ultimately, cash, without allowing the cost of growth to erode profitability.

For the six months ended September 2026, Nigeria’s mobile-services revenue increased 44.6% in reported dollars to $1.008 billion. Underlying EBITDA rose faster, climbing 49.2% to $586 million, while the half-year margin improved to 58.2% from 56.3%.

Those comparisons qualify the quarterly warning. Airtel Nigeria’s earnings are not shrinking, nor has the business lost the benefits of scale. Over the half-year, faster EBITDA growth indicates that rising revenue and cost efficiencies continued to support profitability.

That approach reflects management’s established strategy. 

“During the quarter, we accelerated investment to enhance coverage and data capacity while also expanding our fibre network,” Airtel Africa CEO Sunil Taldar said, commenting on the nine-month results for the period ended December 2025.

The latest results show that investment is continuing. But they also illustrate the financial discipline required to ensure that a larger network produces attractive returns.

Currency movements strengthened the reported performance. The weighted-average exchange rate improved from ₦1,553 per dollar to ₦1,360. Excluding currency movements, mobile-services revenue grew 26.6%, and EBITDA increased 30.7%—still substantial, but below the reported dollar increases. 

A stronger naira, therefore, helped the financial presentation. It should not be confused with an equivalent improvement in operating efficiency.

Fuel margins pressure and the cash stakes

Energy remains a central challenge. In its September 2026 half-year results, Airtel said fuel prices in Nigeria had doubled since the start of the financial year. Revenue growth and efficiency measures nevertheless supported year-on-year margin improvement. The company did not disclose a separate figure for Nigerian fuel or energy expenditure, leaving the actual increase in its energy bill unquantified.

That exposure remains a risk to profitability. “Looking ahead, margin performance will continue to be influenced by the macroeconomic environment, including its impact on fuel costs,” Airtel Africa CEO Sunil Taldar said in the half-year statement. 

Although his warning covered the wider group, the sharp rise in Nigerian fuel prices makes it particularly relevant to the local business.

The tension is straightforward. More customers and higher usage allow an operator to spread infrastructure costs across a larger revenue base. Rising energy expenses can absorb part of that advantage.

Demand remains strong. Airtel Nigeria’s customer base increased 15.1% to 61.7 million, while monthly smartphone data consumption rose from 12.7GB to 16.7GB per customer. Data revenue increased 33.8% in constant currency. 

These figures do not establish that each additional gigabyte became more expensive to deliver. They show that rising consumption coincided with lower quarterly margins, making cost control increasingly important.

Meanwhile, Airtel is spending more to sustain that demand. Nigeria’s first-half capital expenditure rose 139.9% to $177 million. Operating free cash flow increased 28.2% to $409 million—healthy growth, but slower than EBITDA as investment absorbed more earnings. 

The distinction matters. Airtel Nigeria’s operating free cash flow measure already deducts capital expenditure from EBITDA. It is not, however, the same as cash available for shareholders after taxes, financing obligations and other payments.

The wider group demonstrates that gap. Management reported normalised free cash flow of $280 million, down from $368 million, despite stronger earnings, as cash investment accelerated. These are group figures, not Nigeria-only results, but they show why higher EBITDA does not necessarily translate into higher discretionary cash. 

More usage must produce sufficient revenue

Customer spending presents another balancing act. Nigeria’s mobile-services average revenue per user reached $2.80, increasing 28.3% in reported currency and 12.3% in constant currency. 

Management nevertheless acknowledged slower data-ARPU momentum. Newly acquired customers initially consume less, while larger bundles reduce revenue per gigabyte for heavier users. Airtel described its pricing approach as “more for more” and said it had not seen evidence of a price war. 

Encouraging consumption can strengthen customer relationships, but traffic growth does not necessarily generate proportional revenue growth. Airtel Nigeria must earn enough from that usage to justify additional capacity without weakening its offers.

Its results still support confidence: half-year margins and operating free cash flow improved. The quarterly decline is a warning to monitor, not proof of a failing model. The next test is whether disciplined spending and operating efficiencies can preserve the financial returns that Airtel’s expanding network is intended to deliver.

When Nigeria’s president, Bola Tinubu, signed the Designation and Protection of Critical National Information Infrastructure (CNII) Order in June 2024, the Federal Government aimed to shield telecommunications assets from relentless vandalism and physical damage. By classifying fibre lines, base stations, and data centres as vital national security installations, the order sought to impose deterrent penalties and curb unauthorised tampering.

Yet two years on, chronic breaches continue to impose steep financial penalties on operators, diverting capital from network expansion to nonstop emergency repairs and destabilising internet reliability across the country.

In 2023, before the order, MTN Nigeria suffered more than 6,000 fibre cuts in a single year—averaging roughly 16-17 severed lines per day. 

Fast-forward to 2025, past the presidential order: the numbers increased; between January and July, the telco recorded 5,478 fibre cuts. That pushed its daily average to over 26 snapped cables. 

In plain terms, instead of scaring reckless diggers and vandals away and improving coordination between construction firms and other key stakeholders, the new rules led MTN Nigeria to fix about eight more broken cables per day than before the order was introduced.

The broader telecoms industry recorded 19,384 cuts between January and August 2025, further pushing the daily average to 80. In the first nine months of 2026 alone, Telecom networks suffered over 44,000 fibre cuts—averaging more than 160 cuts every single day, mostly from uncoordinated road construction, ditch digging, and theft. The primary culprits remain uncoordinated civil engineering projects, road expansions, and persistent vandalism.

These disruptions expose significant enforcement gaps, raising a central question of who ultimately pays when statutory protections fail to stop contractors and vandals from repeatedly severing the nation’s digital backbone

Building on Tinubu’s signing of the executive order, the legal framework establishes vital statutory mechanisms to defend the nation’s digital backbone.

Under the CNII Order, telecommunications assets—including submarine landing cables, terrestrial fibre-optic lines, switching centres, and data storage hubs—are formally designated as vital national security installations.

The framework empowers security agencies, led by the Office of the National Security Adviser (ONSA) and the Nigeria Security and Civil Defence Corps (NSCDC), to monitor, inspect, and defend digital infrastructure against willful destruction, uncoordinated civil works, and cyber-physical intrusions.

Even so, its ultimate success hinges on swift and consistent prosecution.

Fibre cuts drain expansion capital

Constant network degradation forces telecommunications operators to absorb substantial operational costs, squeezing capital investment. In the first half of 2026, direct repairs across 5,934 fibre incidents cost operators over ₦2.2 billion ($1.64 million).

These emergency expenses undermine the ₦2.13 trillion ($1.58 billion) in capital expenditure committed by network and tower companies, diverting critical resources from new rollouts to restoring existing footprints.

This financial drain has a long track record; it is not new. According to the GSMA Nigeria Digital Economy Report, MTN Nigeria spent ₦11.1 billion ($8.26 million) repairing and relocating 2,502 kilometres of fibre across 2022 and 2023. That figure comprised ₦4.4 billion ($3.27 million) for 1,069 km in 2022 and ₦6.7 billion ($4.98 million) for 1,433 km in 2023—money that GSMA notes could have funded 870 kilometres of greenfield fibre in underserved communities.

Across the wider industry, losses in 2023 alone reached an estimated ₦27 billion ($20.08 million) in direct repairs and lost revenue.

The economic stakes are huge for a country where its ICT sector delivered over ₦6 trillion ($4.46 billion) in real output in Q2 2026, with telecoms contributing 9.72% (₦5.20 trillion / $3.87 billion) to total real GDP: every severed cable is no longer just a temporary network glitch, but an immediate drag on national GDP.

Connectivity gap worsens local challenges

Nigeria’s infrastructure struggles unfold against broader regional constraints. A recent GSMA report on African spectrum policy highlighted that African operators averaged 570 MHz of spectrum below 7 GHz in 2025—far below the global baseline of 750 MHz—while paying 24% more per unit of spectrum. GSMA cautions that every 10% increase in spectrum costs relative to revenue trims 5G coverage expansion by six percentage points.

Fast 5G networks require robust underground cabling to ensure that banking apps, POS machines, and online money transfers work instantly and without failure.

Underlying infrastructure carried massive financial volumes in early 2026: transactions on the Nigeria Inter-Bank Settlement System (NIBSS) surpassed ₦1.053 quadrillion ($783.2 billion) in Q1 alone, alongside millions of daily mobile money and point-of-sale payments. Governed by a 23-year-old regulatory model dating back to the 2G voice era, the sector is directly threatened by physical fibre cuts, which directly threaten overall financial stability.

Fibre backhaul links network base stations directly to core data centres. When cables are cut, the impact cascades into dropped voice calls, crippled data throughput, and widespread service outages.

For enterprises, cuts mean payment gateways collapsing, staff hours lost, and cloud downtime. For subscribers, disruptions translate into sluggish connections, failed payments, and paying higher rates for diminished service.

These disruptions compound consumer frustration following the NCC’s tariff revision, which permitted price hikes of up to 50% to offset soaring operational costs. When operators sink recurring revenue into avoidable repairs, network optimisation stalls, and users pay the price through degraded reliability.

Why has the CNII Order not solved the problem?

The NCC acknowledged the continuing challenge of stakeholder coordination in its August 2026 intervention: “Our interests are aligned; what has too often been missing is a dependable system of early coordination,” said the Executive Vice Chairman of the Nigerian Communications Commission, Aminu Maida.

But coordination can only work when manpower is adequate. The NSCDC’s limited manpower and operational resources expose the enforcement challenges facing one of Nigeria’s agencies tasked with protecting critical national infrastructure.

With roughly 63,000 personnel deployed across 774 local government areas to manage a broad range of national security duties, dedicated static protection for thousands of kilometres of buried fibre is logistically impossible. Even with its efforts on surveillance technology and systematic prosecution, legal protection on paper cannot secure infrastructure without adequate personnel.

The government must therefore measure the success of the CNII Order by tangible results: fewer cuts, faster remediation, and lower repair bills. Until enforcement deters would-be offenders, operators will keep burning through capital on repeated repairs instead of expanding coverage—leaving subscribers to foot the bill for an unprotected digital economy.
